Victor 0781-3631 Regulator

The Victor 0781-3631 is a single-stage brass gas regulator built for natural gas and propane cylinders. It fits a CGA-510LP inlet and delivers adjustable outlet pressure from 2 to 40 psi through a 9/16 in. -18 M LH connection. A 2-inch gauge shows supply pressure up to 400 psi. The neoprene diaphragm and brass body meet ASTM G175, CGA E-4, ELT and UL252 standards.

Cylinder-to-torch pressure control

This regulator replaces a missing or worn single-stage unit on a propane or natural gas supply cylinder. The jump is worth it when the existing regulator cannot hold a steady 2 to 40 psi delivery range or when the inlet connection does not match CGA-510LP. It upgrades setups that lack a 400 psi supply gauge or certified compliance with the listed standards.

2–40 psi delivery range

The regulator comfortably handles torch and heating tips that operate within the 2 to 40 psi delivery window and a maximum inlet pressure of 350 psi. It runs out when the application demands pressure above 40 psi, a different inlet thread, or a two-stage design for ultra-stable output as cylinder pressure drops. The 3.6-inch body diameter fits standard mounting brackets.

Questions about this item

Will the 9/16 in.-18 M LH outlet thread onto my existing hose fitting?

Yes, the regulator outlet is a 9/16 in.-18 M LH thread designed for standard left-hand fuel-gas hose connections.

What is the correct way to open the cylinder valve so the diaphragm isn't damaged?

Back the adjusting screw out fully, then crack the cylinder valve slowly before turning the screw in to the desired 2 to 40 psi delivery range.

How often should the neoprene diaphragm and inlet filter be inspected or replaced?

Inspect the neoprene diaphragm and inlet filter at least annually; replace them if you see cracking, swelling or debris that restricts flow.
